You don’t expect to find one of the Bay Area’s best sushi restaurants sharing an office plaza with a state adoptions office, its back patio overlooking a golf course putting green. But Hana is the real deal. “I eat here at least once a week,” says Pax Mahle, winemaker at Wind Gap, of Tokyo native Ken Tominaga’s place. A big selling point is the presence of Stuart Morris, one of a mere handful of Kikisake-shi (sake master sommeliers) in America. “Sit at the counter and order the omakase with Stu’s sake pairings,” advises Mahle.
